VapeWholesaleHubMod Sampling Programme: How to Evaluate Before You Commit — New Distributors
This page is written for the person who has to sign the purchase order, not for the person who designed the packaging. If you are weighing up mod right now, the sections below follow the order in which the real decisions tend to arrive.
What to Fix Before Approving Mod
Revisit the mod specification after every third order. Small improvements compound, and factories take a buyer more seriously when the document has clearly been used.
| Product category | Closed pod |
|---|---|
| Resistance band | 0.6 - 0.8 ohm |
| Capacity tolerance | +/- 3% |
| Puff count method | Declared by capacity |
| Master carton | 240 units |
| Carton weight | 5.0 kg |
| Shelf life | 24 months |
| Storage | 15-25 C, dry, away from direct light |
Market Signals
The most durable mod lines over the last few years have been unglamorous and consistent. Novelty sells once; reliability sells every month.
Pricing and Margin
When you model mod pricing, build in a realistic shrink figure. Even a well run line loses a small percentage to damage, expiry and sampling. Pretending that number is zero is how a healthy looking margin turns negative.
Indicative reference points for planning purposes: entry tier from USD 1.74 per unit at 2000 units, mid tier at USD 1.74, and volume tier at USD 1.00 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
How Mod Batches Are Checked
AQL sampling gets a lot of attention, but for mod the more useful habit is simply measuring the same three things on every single batch. Trend lines catch problems that pass/fail checks miss.
Train whoever receives mod cartons to note anything unusual at the point of unloading. Damage discovered at the dock is a freight claim; damage discovered a week later is your problem.
- Agree the tolerance band in writing before approving artwork.
- Start with a mixed carton and let your own sell-through decide.
- Check carton dimensions against your freight quote before confirming.
- Write the complaint threshold into the order terms.
- Plan the switch from air to sea freight before you need it.
Selling Mod at Store Level
Use your mod staff training time on the two questions customers actually ask. Anything more detailed gets forgotten by the second shift.
Getting Mod to Your Warehouse
Track mod landed cost per unit as a running number, including duty and local delivery. It is the only figure that tells you whether a supplier change actually improved anything.
Practical Checklist
- Write the complaint threshold into the order terms.
- Rotate stock by batch code rather than by delivery date.
- Model landed cost, not ex-works price, when comparing quotes.
- Keep sealed retained samples from every production batch.
- Ask how the factory measures puff count, then compare like with like.
- Check carton dimensions against your freight quote before confirming.
Frequently Asked Questions
Is there a warranty on mod?
Manufacturing defects are covered against the retained sample standard. Normal wear, misuse and damage after opening are not. We publish the threshold in the order terms so both sides know exactly what the claim process looks like.
What does a sample pack usually include?
A typical mod sample pack covers the strengths or variants you are most likely to list, packed so you can evaluate them side by side. Tell us which lines you are considering and we will match the pack to that rather than sending a generic selection.
Can I visit the production facility?
Yes, and we encourage it for larger programmes. Visits are most useful when you already have a draft specification, because you can then check the specific processes behind the numbers you care about.
How should mod be stored?
Cool, dry and out of direct sunlight. Heat and light are the two things that shorten shelf life fastest. Rotate stock by batch code rather than by arrival date, and keep cartons off concrete floors in humid warehouses.
Next Step
If you are comparing options right now, send us the specification you have been quoted elsewhere. A side by side reading usually shows where the price difference actually comes from, and that is the most useful first conversation to have.
